Anomalous Nernst Effects of [CoSiB/Pt] Multilayer Films

Journal of Magnetics, 2013
We report a measurement for the anomalous Nernst effects induced by a temperature gradient in [CoSiB/Pt] multilayer films with perpendicular magnetic anisotropy. The Nernst voltage shows a characteristic hysteresis which reflects the magnetization of the film as in the case of the anomalous Hall effects.

Sign change of anomalous Hall effect and anomalous Nernst effect in the Weyl semimetal CeAlSi

Physical Review B, 2023
We report the anomalous Hall effect (AHE) and the anomalous Nernst effect (ANE) data for the noncollinear Weyl semimetal CeAlSi. The anomalous Hall conductivity (σA i j ) was measured for two different orientations of the magnetic field (B), namely σA yz for B||a and σA xy for B||c, where a and c denote the crystallographic axes. We find that σA xy and

Anomalous suppression of Nernst effect in La0.7Ca0.3MnO3

Solid State Communications, 1999
Abstract We report on the magnetization, colossal magnetoresistance (CMR), thermoelectric power (TEP) and Nernst coefficient (Q) measurements of a La0.7Ca0.3MnO3 bulk ceramic sample (Tc∼265 K). The semiconductor—metal transition near Tc is attributed to an increase in the hole density.

First-principles study of anomalous Hall effect and anomalous Nernst effect in Fe₂Si

Japanese Journal of Applied Physics, 2023
Abstract We have performed density functional calculations of the electronic structure, anomalous Hall conductivity, and anomalous Nernst conductivity for the model crystal structure of a mineral Hapkeite Fe2Si contained in a meteorite Dhofar 280, which is believed to originate from the Moon.

Anomalous Nernst effect of a ferromagnetic film on a semiconductor

Applied Physics Letters, 2020
Measuring the anomalous Nernst effect of magnetically ordered thin films on substrates is often hampered by the mismatch between different thermal conductivities and the unknown temperature gradient in the film. Here, we demonstrate that for ferromagnetic films deposited on a semiconducting substrate, the Nernst effect of the semiconductor can serve as

Absence of the thermal Hall effect in anomalous Nernst and spin Seebeck effects

2017 IEEE International Magnetics Conference (INTERMAG), 2016
The anomalous Nernst effect (ANE) and the spin Seebeck effect (SSE) in spin caloritronics are two of the most important mechanisms to manipulate the spin-polarized current and pure spin current by thermal excitation. While the ANE in ferromagnetic metals and the SSE in magnetic insulators have been extensively studied, a recent theoretical work ...

Spin Nernst and anomalous Nernst effects and their signature outputs in ferromagnet/nonmagnet heterostructures

Physical Review B, 2020
The spin Nernst effect (SNE) and anomalous Nernst effect (ANE) convert a heat current generated by a temperature gradient to a spin current in nonmagnetic metals and ferromagnets, respectively. We present a diffusive spin transport theory of the combination of these thermoelectric effects in ferromagnet (F)/nonmagnet (N) heterostructures and their ...

Anomalous Hall effect and Nernst effect in itinerant ferromagnets

Journal of Magnetism and Magnetic Materials, 2007
Abstract Anomalous Hall effect (AHE) and anomalous Nernst effect (ANE) in many ferromagnetic metals including pure metals, oxides, and calcogenides, are studied to obtain unified understandings of their origins. We show the universal behavior of anomalous Hall conductivity σ xy as a function of longitudinal conductivity σ xx
